Referring to Figure 4 showing a pipe coupling,

In this cone ri g to ur 1 the P p union struction coupling member 3l comprises two 30 p s an entrance end member ii having an parts only, an internally threaded entrance end enla ed periphe flange l2 at its lime! end 32 and an exit end 33 which is similarly internalup which 8.iirii0n up l3 having an interly threaded so that two pipes may be connected nal flan ll for em n with flan I2 is thereby.

The valve in'the union is preferable 65 The cen r l Op off s valveca e is PIO- since the union permits a disconnection of the coupling without the necessity of removing the pipes or disconnecting either of the ends II or II by merely turning the universal coupling member ll until the threaded joint I. is opened so that it can slide back over the end ll of the union [I and permit the cylindrical member I! which carries the valve cage, also the valve members to be entirely removed or replaced.

In either form the coupling member is adapted for use in either horizontal or vertical position and naturally if in a vertical position' or sloping position it is operable only to check a backward flow in a normally ascending flow of liquid through the conductors or pipes.

It will be yObViOllS to those skilled in the that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit myself to what is shown in the drawing and described in the N specification, but only as indicated by the ap-- pended claims. I claim:

1. In combination, a pipe union comprising a pair of threaded pipe receiving end members, a

aoe iaa union connector mounted to swivel on one of said end members and hfiving a threaded joint connection with the other end member, a cylindrical member mounted in said union connector and held therein between the inner ends of said end members, said cylindrical member having a valve cage and valve seat at one end thereof, a valve member in said cylindrical member coopcrating with said valve cage and seat, said valve havinga central projection thereon, and a spherical ball member also insaid cylindrical member cooperating with the projection onthe valve member insuring the proper seating of the valve in the valve seat.

. 2, A pipe coupling having a cylindrical interior, a valve seat therein} a valve adapted to seat on said valve seat, a central projection on a face of said valve, and a spherical ball loosely positioned in said cylindrical interior adapted to engage therewith and cooperate with the projection on the valve to insure a force applied centrally thereto in eifecting its seating in said valve seat.
